we have a big problem, my hardware are two host XenServer 5.6 server IBM x3850 with Dual Port 10GbE FCoE (qle8152) and switch Cisco nexus 5020

For the CNA driver I followed this instructions:

After reboot, I have the new ethX (FCoE) and everything seems to work fine.
But we have a big problem only if we use the nic FCoE (10GbE) with the vlan trunking.
(after configuring the switch and create the vlan on both XenServer)
- If I create 2 VMs on the same VLAN and on the same host, they can talk to each other (ping and ssh and all protocols work correctly)
- If I create 2 VMs on the same VLAN on different hosts they cannot talk to each other (ping are OK but ssh and all protocols TCP do not work properly)
We have tested on RedHat5.5 with xensource (on the same hardware) and the VM (with vlan trunking) are ok.
But we want to use XenServer 5.6 and buy the license to use the support because we have buy many hardware.

We opened a case to qlogic 

Citrix has also opened a problem

Any idea ?
